| 摘 要： | 通过对地层层序、生物群组成的分析 ,认为云南曲靖地区玉龙寺组的时代为晚志留世 ,大致与 Pridoli的早中期相当。从岩石地层、生物群分析以及构造运动等因素考虑 ,认为目前志留系 -泥盆系界线划在玉龙寺组顶部黑色页岩与西山村组底部中厚层砂岩之间较适宜

| Abstract: | Based on the stratigraphical sequence, the composition of biota, tectonism and some new findings of invertebrate fossils, and the distribution of fish fossils,the age of the upper black shale of the Yulognsi Formation is regarded to be Late Silurian,most probably Pridolian,and the Silurian Devonian boundery in East Yunnan should be drawn between the top of the Yulongsi Formation and the base of the Xishancun Formation. |
